Abstract: 570,745. Cracking hydrocarbons; catalytic processes. STANDARD OIL DEVELOPMENT CO. Nov. 11, 1942, No. 15926. Convention date, Oct. 21, 1941. [Classes 1 (i) and 32] [Also in Group XXIX] Control of the rate of flow of a solid in suspension in a fluid, e.g., catalyst in suspension in vapors of a hydrocarbon oil which is to be cracked or otherwise catalytically treated, is obtained by passing the suspension through the tubes 36 of a heat exchanger 66 around which a cooling liquid is circulated, measuring the temperature of the incoming and outgoing suspension and similarly the temperature of the incoming and outgoing heat exchange liquid, and from these data and the known specific heats of the catalyst, hydrocarbon vapors, and heat exchange liquid calculating the flow rate of the solids, i.e., catalyst, and from these values controlling the residence time of the catalyst in the reaction zone. The exit and inlet temperatures of the suspension and heat exchange liquid are measured by thermocouples 110, 111, 120, 121 connected to a recorder 115. An automatically operated flow control valve 130 and orifice meter 135 control the flow of cooling fluid. The apparatus may be used in conjunction with a plant for the catalytic conversion of gas oil to gasoline, comprising a supply conduit for gas oil 1 leading to a heating coil 3, the vaporised oil being mixed with catalyst from a separator 12 in an injector 10, and the suspension obtained passed through a reactor 25. The cracked products are separated from catalyst in a separator 42 and subjected to fractionation in a column 90 to recover gaseous hydrocarbons overhead through line 92, gasoline through line 100, light gas oil through line 94, and recycle oil through line 46 to an injector 50 from which in admixture with oxidising gases it is passed through a regenerator 60 and thence through a heat exchanger 66 to the separator 12. Reference has been directed by the Comptroller to Specification 131,375, [Class 69 (i)].

Abstract: 1,210,019. Direct current smoothing circults. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 5 April, 1968 [8 April, 1967], No. 16540/68. Heading H2F. An EHT supply to a cathode-ray tube is smoothed by use of a series resistor having a negative temperature co-efficient. As described, the EHT supply for a colour television tube, an electron microscope or an X-ray tube, is generated by periodically interrupting the current in a transformer and rectifying the resulting high voltage pulses by means of a voltage-doubling or other valve or semiconductor rectifier. The EHT is smoothed by a reservoir capacitor, the negative temperature co-efficient resistor and a smoothing capacitance formed by the outer coating of the cathode-ray tube or by the coaxial cable connected thereto. In event of a short circuit, the resistance of smoothing resistor drops sufficiently to allow a protective fuse to open.

Filed: 1938-06-02
Abstract: 508,255. Supply systems for induction furnaces. BRITISH THOMSON-HOUSTON CO., Ltd. June 2, 1938; No. 16555. Convention date, June 2, 1937. [Class 38 (iv)] In a two-phased or multi-phase coreless induction furnace regulation of either the magnitude or the phase, or both, of the voltages feeding the furnace windings is effected by way of a Scott transformer 14, Fig. 4, preferably in auto-connection in such a way that one furnace winding, e.g. winding 11, is connected permanently to the upright winding 17 or to one of the basis windings 18, 19, whilst the other winding, 12, to be regulated is, in the case of a two-phase winding, connected across the upright winding 17 and one of the basis windings, e.g. winding 19, regulation being effected by means of tappings on the upright or basis windings. The upright winding 17 is prolonged at 20 beyond the windings 18, 19 in order to provide adjustment of the relative vector positions of the voltage. Fig. 5 shows a vector diagram of the voltages, wherein 24 represents the vector direction, assumed to be invariable, of the voltage feeding the winding 11. The winding 12 is connected between the lefthand end of the winding 19 and one of the tappings 21 of winding 17 or of the tappings 22 of the prolongation 20, so that by starting from the topmost tapping 26 and switching gradually through to the bottom tapping 27, the vector position of the voltage is changed within the range of the vectors 25, through 25<1> to 25<11>. A pole-reversing switch 23 provided on winding 12 enables these voltage vectors to be turned 180‹ to assume the angles alpha<1> to alpha<111> relatively to the voltage at winding 11. To avoid alteration of the magnitude of the voltage supplied to the winding 12 the winding 19 may be provided with tappings from which the feed conductor 28 of the winding 12 may be tapped off in each particular case. A third winding may be provided on the furnace and connected to one of the tappings 21 of the winding 17 and to the winding 18. Since asymmetry results from the adjustment of the winding connections, equalizing reactive circuits, preferably capacitative, may be provided, which may be controlled either manually or automatically by known methods. Heating and mixing of the molten bath of low frequency current may be effected simultaneously with high frequency heating, such a circuit arrangement being shown in Fig. 9. A high-frequency generator 43 working at a frequency of 600 kcs. or higher is connected through suitable switches to either of the windings 11, 12 or to both simultaneously. A condenser 44 is provided to tune the frequency of the associated winding to the working frequency of the generator 43. Blocking circuits 45 tuned to current resonance are provided to prevent the H.F. currents from entering the low-frequency circuit. An inductance 46 tuned to current resonance as regards the network 15 is placed in parallel with the condenser 44 to prevent low-frequency currents from entering the H.F. circuit.
